SEL’s new falling conductor mitigation solution

SEL recently released a new broken conductor mitigation solution, which detects breaks in overhead distribution lines and de-energizes them before they hit the ground, preventing wildfires and other hazards. This falling conductor mitigation solution was developed in collaboration with San Diego Gas & Electric Company (SDG&E) and Quanta Technology.

The solution is based on specialized algorithms implemented in SEL Real-Time Automation Controllers (RTACs), field devices streaming synchrophasor data, and high-speed communications. By continuously analyzing phasor data in real time, the RTAC can reliably identify conductor breaks and send commands to trip the affected section within fractions of a second. With simple template-based settings, this solution can easily be adapted and expanded for additional feeders and phasor measurement units (PMUs).
